5 Installation Guide5.4 LubricationProper lubrication practices will greatly extend the life of the bearing.Bearings are factory lubricated with the proper amount and type of lubricant for most general purpose applications as wellas many highly demanding operating environments, and except as recommended by FYH, no further lubrication is requiredupon installation.Lubrication tips:• The factory standard lubricant is a Calcium Sulfonate grease. Always use the same type of lubricant to avoid compatibilityissues and other potential problems.• When adding lubricant do so slowly and while the bearing is rotating until a small amount of lubricant can be seen comingout of the seals.• At low speeds (below 200 RPM) it is acceptable to completely fill the bearing with grease.• At moderate to high speeds it is not advisable to completely fill the bearing with grease as it could lead to overheating andreduced bearing life.• It is generally better to use less lubrication more frequently than more lubricant less often.• If the unit will not be operated for an extended period of time extra lubricant should be added to prevent corrosion.• If the unit has not been operated for an extended period of time fresh lubricant should be added prior to start-up.• If the unit becomes too hot during operation from over-lubrication remove the grease fitting and operate the unit forapproximately thirty minutes to allow excess grease to purge.Appropriate lubrication intervals can be determined by referring to Table 5; however experience should largely determinethe actual lubrication regimen for a particular application. Consult with an FYH representative for assistance.If a suitable Calcium Sulfonate lubricant is not available for re-lubrication then the following compatible lubricants may alsobe used:Barium Complex, Calcium Stearate, Lithium Complex, Polyurea (Shear Stable)The use of any other type of lubricant should be avoided to prevent compatibility issues with the Calcium Sulfonate greasethat is originally supplied.To find the proper lubrication interval in Table 5 obtain the relevant percentage of max allowable RPM by referring to Table 6.Example: XS411 with positive contact seals has a max RPM rating of 2000. If the application has an RPM of 600 then thepercentage of max RPM is 30% (600/2000 = .30).The amount of grease for replenishment can be found in Table 7.Table 5 - Lubrication ScheduleEnvironment Clean to Moderately Dirty Clean to Moderately DirtyTemperature(°C)% of maxallowable RPMLubricationintervalUnder 120 degreesOver 120 degreesDirty to VeryDirtyFrom -20to 2000 - 25% 25 - 50% 50 - 75% 75 - 100% 0 - 25% 25 - 50% 50 - 100% 0 - 100%From three toeight monthsFrom one tothree monthsFrom one weekto one monthDaily to onceper weekFrom two to sixweeksFrom one weekto one monthDaily to onceper weekDaily to onceper week336
